I have some problems with your story.

1)All side branch members have a curse mark that will kill them if they are ever in enemy hands. I also don't think the timing is right as there is only chunin exam that happens is the filler one and the timeline does not quite add up. Also why would Obito kill saskue and give his body to orochimaru but for pedo reasons? when Itachi and Obito are all like sharigan bros into the moon tree plan while being a spy for the leaf? and Obito wanted saskue to join him.

2)If Obito dies then no one is alive to set up the moon tree plain. And then no 5 kage battle and then Danzo is hokage of the leaf with no saskue to kill him. after Danzo trying to use genjutsu on the other kages at the meeting is found out by AO's bykugan. Danzo would be killed at the meeting by AY or if he did excape with izangai all nations would be after the leaf that is still rebuilding after the attack.

3)Obito is dead so no team up with kabuto so no white zetus army Kabuto can still use edo tenis on the orignal sound 3 lead by Dosu (Who turns out is a elite who was on par with Orochimaru him self) who after learning from his mistake of going toe to toe with full power Shukaku in the part that the anime faded away from that was a epic battle that was even bigger then the one with pain.

4)How does Deidara a guy who only cares about *ing things up get trusted with running a ninja village? when he was wanted in the earth ninja village he came from for trying to * it up. he also tried to * up the sand village. So how dumb is konan for letting him in the rain village? so Deidara betraying her is her own fault. Also Sasori hates waiting naruto online told me that.

5) There is no GNW with no shinobi alliance from the 5 kage battle as everyone hates the leaf. Kabuto can still summon Madera but he would not know what he was doing there. Black zetus failed with saskue being dead so no way for kaguya to show up with the moon eye plain being failed. and all the villages live with the rest of the time never coming togeter if anything fighting more after how bad Danzo screw up the meeting. and it is only a matter of time before the 3 arts are hunted down by AO and Dosu for some reason.

Also Spoiler Obito is Tobi

Well he get the sharingan at some point in the boruto part with shin. not sure where he got it from but Obito did have a collection of sharingan.
